An underwire bra (also under wire bra, under-wire bra, or underwired bra) is a brassiere that utilizes a thin, semi-circular strip of rigid material fitted inside the brassiere fabric. The wire may be made of metal, plastic, or resin. The wire helps to lift, separate, shape, and support a woman's breasts.
The underwire should surround the whole under part of the breast and never press against the breast tissue at the side or in the middle. You should be able to lift your arms up without the underwire gliding up. If it does, the circumference of your bra is too big.
It's available in different cup and back sizes and should be worn in the correct size. This may vary as women breasts and bodies change. To get the perfect fit book a free bra fitting with us.
